documentation/dev-manual/dev-manual-kernel-appendix.xml: Fix PARALLEL_MAKE

Every place in the YP documentation suggests setting BB_NUMBER_THREADS
and PARALLEL_MAKE to twice the number of cores as the host machine.
This fixes a single instance in the YP dev manual where it was
suggested that PARELLEL_MAKE be set at 1.5x times the number of
cores.

If your host development system supports multi-core and multi-thread capabilities,
you can uncomment these statements and set the variables to significantly shorten
the full build time.
As a guideline, set <filename>BB_NUMBER_THREADS</filename> to twice the number
of cores your machine supports and set <filename>PARALLEL_MAKE</filename> to one and
a half times the number of cores your machine supports.
As a guideline, set both the <filename>BB_NUMBER_THREADS</filename> and the
<filename>PARALLEL_MAKE</filename> variables to twice the number
of cores your machine supports.

The following two commands <filename>source</filename> the build environment setup script
and build the default <filename>qemux86</filename> image.
